Question

v=u+at (m\s)
v=20,a=5,t=2,u=? ​

Answer 1

Answer:

20= u + 5×2

20=u+10

u=10

Answer 2

Answer:

u = 10 m/s

Explanation

Given

Final velocity(v) = 20 m/s

acceleration(a) = 5 m/s²

time(t) = 2 sec

To Find

Initial velocity(u)

Solution

From the equation of motion

$\blue{\boxed{\pink{v=u+at}}}$

20 = u + 5(2)

20 = u + 10

u = 20-10

u = 10 m/s
